In males with premature (early) ejaculation and no other medical problems, no specific conventional laboratory tests aid or affect treatment. Checking the patient’s levels of serum testosterone (free and total) and prolactin may be appropriate if premature ejaculation is observed in conjunction with an impotence problem. If depression or other conditions coexist, laboratory studies specific to depression or to another medical or psychological problem are appropriate.
